Testosterone check

Testosterone testing made easy. Take our simple home finger prick blood test to check your testosterone levels quickly and easily.

Check whether you have high or low testosterone with our simple blood test you can take at home and then post to our lab for scientifc analysis. Testosterone plays a key role in your body, affecting the brain, bone and muscle mass, fat distribution, the vascular system, your energy levels and sexual functioning.

In the case of women, only low levels of testosterone should exist within the body. Elevated testosterone in women can result in significant physical effects and can lead to fertility problems.

We recommend you take your testosterone blood test in the morning, as your testosterone levels fall over the course of the day.

Why measure testosterone?

You might take a testosterone blood test if:

  • You’re a woman experiencing fertility problems and you would like to rule out high testosterone levels
  • You’re a male experiencing low libido problems
  • You’re a male seeking to improve energy levels, strength and stamina

Benefits of testosterone check

Taking a testosterone blood test can help men to identify the cause of low libido, a fall in energy levels or low strength and stamina.

For women, it could help to identify fertility problems or other physiological issues.

In both cases, establishing your levels of testosterone is a positive first step towards treating any issues and ultimately eliminating the symptoms caused by low or elevated levels.

For those already undergoing lifestyle changes (like weight loss) or medical treatment to improve testosterone levels, this test can be a quick and simple way to track your levels over time.

With our testosterone blood test kit, you simply carry out the finger prick test at home, post it direct to our lab and you’ll have your results in a clear and easy to understand digital dashboard in a matter of days.

What our customers say

As a former Olympic cyclist I always wanted to look after my health. This has never changed to this day but become a lot easier via Forth, it’s the only way to really understand your own body. 

Brian Smith

As a working mum, I often find myself training ‘tired’ as the demands of day-to-day life take their toll.  Forth has enabled me to gain a valuable insight into what is happening ‘under the surface’, so I  can adapt my training and lifestyle.

Kate Allan

I ran my first marathon in 2014 which left me feeling exhausted and constantly unwell. What I didn’t know then was that my iron and vitamin D levels were incredibly low.  By using Forth to test key biomarkers has put me in control of the areas I need to improve.

Jude Peck, 42

I enlisted the help of Forth to help me get to the bottom of my current health concerns. The test was really easy to and my results were available within day. Using Forth has helped me take the action needed to get my hormones back on track.

Holly Rush, 39

I suffer from a hereditary condition which causes my body to store too much iron.  My biggest issue before using Forth was getting an appointment with my GP.  Now using Forth I can track my iron quickly and easily and take action before levels start to affect my health

Mark Threfall, 29

Forth really helped me understand issues that I was having, which in the end turned out to be problems with iron absorption. Without their test I would never have known this. I now have the knowledge I need to improve.

Sean Conway

I was keen to use Forth’s service to help monitor my haematological markers in particular since I've had problems in the past and by the time they are picked up by the GP I'm normally feeling unwell.  The test was quick and easy to do and results were back very quickly. The results are also incredibly accurate, being almost identical to those from tests done by my GP the same day.

Alice Lethbridge

I'd put off getting regular blood tests before because of the long-winded process of a GP visit. Forth has changed all that. The process is very quick and very easy, with thorough, well-explained results delivered to your inbox within days.

Alice Hector

Taking the test is simple just make sure you follow all the instructions so you follow the correct procedures. The customer service is second to none and the results are easy to understand and follow.
